The minerals licensed for exploration in this case are base metals, barytes and zinc. I am informed that the company is currently carrying out an approved programme of drilling in the area, employing five drilling rigs. In carrying out all such activities within the licensed area, it is a strict condition that the licensee must conduct operations so as to avoid damage to the environment and the amenities of the area, to avoid or minimise disturbance of persons resident there and comply with all relevant statutory planning and environmental requirements.
